EML3276

ESMT EML3276 5.0A, Synchronous Step-Down DC-DC Converter General Description EML3276 is a high efficiency, DC-DC synchronous buck converter which provides 5.0A output loading after output voltage reach preset voltage. EML3276 uses different modulation algorithms for various loading conditions. Under heavy load, EML3276 regulates the output voltage using Pulse Width Modulation (PWM). The PWM mode provides low output voltage ripple and fixed frequency noise. While in light load, it enters Power Skip Modulation (PSM) automatically to ensure a highly efficient operation at light load condition. Under very heavy load condition, or when the input voltage approaches the output voltage, EML3276 enters low dropout voltage operation under 100% duty cycle. The internal generated 0.8V precision feedback reference voltage is designed for low output voltage request. Low Power-FET Ron synchronous switch dramatically reduces conduction loss. The EML3276 is available in an 8-pin, space-saving E-SOP-...
